In a mixing bowl, combine 2 cups flour, 2 tsp. baking powder, 1/2 tsp. baking soda, and 3/4 tsp. salt. In a liquid measuring cup, stir together 1 cup cold milk and 8 Tbsp. butter (melted and slightly cooled). Pour the milk/butter mixture into the bowl of dry ingredients. Add 3/4 cup shredded Parmesan cheese.
Line a 8x11 Pyrex dish with parchment paper. Pour in the dough and press into a flat, even
layer. Top with 1/4 cup more Parmesan cheese and freshly ground black pepper.
Bake for 11-13 minutes at 475°.
Lift the parchment paper from the baking dish and cool slightly before cutting into breadsticks.
